In order to convert solar radiation to direct current electricity, it requires the use of PVs, or photovoltaic material. Many different types of material are combined to create the photovoltaic cell. Due to the most recent demand for renewable energy, the manufacture of these cells has dramatically increased. There production has been steadily increasing since 2002 each year. Read on and find out how PV solar is one way to conserve natural resources in the future.
To change the radiation that we get from the sun into electricity, photovoltaics use solar cells. The photovoltaic effect is a process that explains how photons of light force movement of electrons until they are charged and electricity is created. The electricity that is created initially is direct current, and to use it in most instances, it is converted with an inverter to alternating current.
Some materials used to make photovoltaics are monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium selenide. Polycrystalline is one key component of the solar panel, and panel creation is limited to the amount of its supply. In 2006, over half the supply in the world was being used for solar panels. In 2008, there were twelve factories producing polycrystalline.
The production of PVs has increased by at least twenty percent per year beginning in 2002. That labels it as the fastest growing energy technology in the world. By the end of 2009, worldwide, installed PVs totaled more that 21,000 megawatts (megawatt=1 million watts).
There are many countries in support of the photovoltaic as a source of renewable energy. In fact, there are several different governments that are providing incentives to both businesses and citizens to install packages. With the advancement of technology and the increase in manufacturing products, the prices have fallen to a more reasonable rate.
In 2008, it was said that solar power could provide one thousand times what the world would need and it only provide two tenths of a percent that year. By these statistics, it is apparent that renewable energy resources have not been used to the fullest; not even close. The prediction is that it will continue to double every two to three years. It could become the main power source for the world.
Some would say that solar power is not predictable, however, they are able to predict with exceptional accuracy when it will and will not be available. Other sources of renewable energy can also be used in conjunction with the photovoltaics. This has been proven successful in large power plants.
